Head: I haven't tried 8000's but I have 8800's I've been skiing since mid season. They are pretty good in crud, I like to do GS+ turns at speed on most terrain (avoid bumps if at all possible). 8800's are passable in bumps, I imagine the 8000's are a lot better. The skis overall are great, I've been able to get bigger air off drops and land with confidence, the width and length helps so much for solid landings and straightlining, altohugh the tips will flap at high speed. They still rail turns on groomers, I don't think I would ever get a ski under 85mm waist again because these at 89 provide enough fun on groomers/hardpack, unless you are racing or only skiing hardpack/bumps theres no need to go thin.
